The utility model is fixed on both sides of the steel box girder through the clamp and the fastening bolt, is convenient to install and disassemble, and can avoid damaging the steel box girder; the guardrail vertical rod can be repeatedly used after being disassembled.
Description
Technical Field
The utility model relates to a steel construction bridge construction technical field, concretely installs the guardrail in the steel box girder both sides, concretely relates to guardrail pole setting of assembled installation.
Background
After the steel box girder of steel structure bridge hoists and accomplishes, when carrying out the bridge floor construction, for guaranteeing constructor safety, need at the interim guardrail of steel box girder both sides installation. Traditional guardrail generally adopts little steel pipe or angle steel as guardrail pole setting lug weld at the steel box girder edge, welds twice reinforcing bar between adjacent pole setting and regards as the guardrail horizontal pole. The method needs on-site welding, cannot be constructed under the influence of rain and snow weather, and needs flame gas cutting for cutting when the guardrail is dismantled, so that not only is material waste caused, but also the base material of the steel box girder can be damaged, and the later repair workload is increased.
Disclosure of Invention
The utility model aims at providing an assembled steel case roof beam guardrail pole setting to the problem that current welding formula guardrail exists, avoids causing the damage to the steel case roof beam to it is extravagant to reduce the material.
The technical scheme of the utility model as follows:
the utility model provides an assembled steel case roof beam guardrail pole setting which characterized in that: comprises a vertical rod body and a U-shaped clamp; the clamp comprises a rectangular upper clamp plate and a rectangular lower clamp plate which are horizontally arranged, an interval which is larger than the thickness of a top plate of the steel box girder is arranged between the upper clamp plate and the lower clamp plate, one sides of the upper clamp plate and the lower clamp plate are connected through a side plate, a fastening bolt is screwed on the lower clamp plate, and the fastening bolt vertically penetrates through the lower clamp plate; the clamp is characterized in that a vertical rod connecting plate is vertically welded on the top surface of the clamp upper clamping plate, and the lower end of the vertical rod body is connected with the vertical rod connecting plate through a bolt.
The utility model adopts an assembly structure, is fixed on both sides of the steel box girder through the clamp, is convenient to install and disassemble, has no welding procedure on the installation site, and can avoid damaging the base metal of the steel box girder; the guardrail vertical rod can be repeatedly used after being detached, and the material waste can be avoided.

Detailed Description
As shown in fig. 1 and 2, the present invention comprises a vertical rod body 1 and a U-shaped clamp 2; the clamp 2 comprises a rectangular upper clamp plate 21 and a rectangular lower clamp plate 22 which are horizontally arranged, a distance which is larger than the thickness of a top plate of the steel box girder is formed between the upper clamp plate 21 and the lower clamp plate 22, one side of the upper clamp plate 21 is connected with one side of the lower clamp plate 22 through a side plate 23, and the other side of the upper clamp plate 21 forms a bayonet; a fastening bolt 3 is screwed on the lower clamping plate 23, and the fastening bolt 3 vertically penetrates through the lower clamping plate 22; the top surface of the clamp upper clamping plate 21 is vertically welded with a vertical rod connecting plate 4, and the lower end of the vertical rod body 1 is connected with the vertical rod connecting plate 4 through a bolt.
The upper end of the fastening bolt 3 is located between the upper clamp plate 21 and the lower clamp plate 22. The utility model discloses during the implementation, can be at backing plate 5 that 3 upper ends welding levels of fastening bolt set up for area of contact between increase and steel box girder roof bottom surface.
In order to facilitate the arrangement of the guardrail cross rods, at least two guardrail cross rod connecting plates 6 can be preset on the vertical rod body 1, one side of each guardrail cross rod connecting plate 6 is connected with the vertical rod body through a bolt, the other side of each guardrail cross rod connecting plate protrudes out of one side of the vertical rod body, and a cross rod inserting hole 61 is formed in each guardrail cross rod.
As shown in fig. 3, the utility model discloses a bayonet socket card of anchor clamps 2 is in 7 both sides of roof of steel box girder, and anchor clamps punch holder 21 is located 7 top surfaces of steel box girder roof, and anchor clamps lower plate 22 is located 7 below of steel box girder roof, upwards screws up fastening bolt 3 on the lower plate, makes fastening bolt 3 upper end top tight steel box girder roof 7 bottom surfaces, and is fixed anchor clamps and steel box girder roof, accomplishes the installation of guardrail pole setting promptly.
Between adjacent guardrail pole setting, through the horizontal pole jack cartridge guardrail horizontal pole on the guardrail horizontal pole connecting plate, or connect the protection rope, accomplish the installation of whole guardrail.
